Trailer utilization systems, methods, computer programs embodied on computer-readable media, and apparatuses

ABSTRACT

The disclosed systems, methods, apparatuses, and computer programs embodied on computer-readable media may enable a shipping carrier to determine the utilization of a trailer in a delivery network by receiving and aggregating disparate types and sources of shipping information, including, for example, package billing data from a customer order, scan data from the loading and unloading of packages transported by the trailer, dimensional data received from dimensional scans of packages at carrier shipping hubs, and/or trailer data including the volume of the trailer. Utilization may be determined for each trailer in a carrier delivery network or for a subset of trailers in the network. The determined utilizations may be used to determine the parameters for an optimized delivery network, which may include the addition, elimination, and/or modification of the delivery schedule. Network optimization may be an iterative process that may be continually performed using continually updated trailer utilization statistics.

BACKGROUND OF THE INVENTION

1. Technical Field

The following disclosure relates to the field of package delivery and, more particularly, to a system, method, computer program embodied on a computer-readable medium, and apparatus for determining the utilization of each trailer in a plurality of trailers for the purpose of optimizing a delivery network.

2. Description of Related Art

In the shipping and delivery industry, many shipping carriers attempt to maximize the utilization of trailers and other shipping equipment in which packages are transported. Utilization often has a significant impact on a shipping operation's efficiency and the shipping costs of a carrier. Accordingly, carriers may measure, track, and monitor the utilization of their trailers in order to attempt to maximize utilization.

Past attempts to measure trailer utilization have involved various methods, including, for example, visual inspection of the packages loaded into trailers. Visual inspection is a less than optimal method for determining utilization of a trailer, as the utilization is merely a visual estimate of the amount of space occupied by packages.

Accordingly, it may be desirable to develop a technique for determining trailer utilization that addresses at least some of these and other issues and drawbacks.

DETAILED DESCRIPTION OF THE INVENTION

The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the inventions are shown. Indeed, these inventions may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.

Overview

The present disclosure, according to various embodiments, may enable a shipping carrier to optimize a delivery network by evaluating the utilizations of the respective trailers, trucks, and/or delivery vehicles (collectively referred to as “trailers”) operating within the delivery network and realigning the delivery trailers and the schedule accordingly. According to one embodiment, a trailer utilization server may be employed to calculate the utilization of a trailer by determining the percentage of the interior volume of the trailer that is occupied by packages that are being transported in the trailer.

The trailer utilization server may determine the interior volume of the trailer, for example, by accessing a trailer database containing “trailer data,” or data identifying, among other things, the interior volume associated with each of the trailers operating within the delivery network. The volume of packages being transported inside of the trailer may be determined by, for example, aggregating package-related data obtained from various different sources at various different times throughout the delivery cycle. In one embodiment, as discussed in more detail below, the package-related data may be stored in one or more databases accessible by the trailer utilization server and may include, for example, “billing data,” or data input by a customer at the time of placing an order to ship a package, “dimensional data,” or height, length and/or width data obtained from a dimensional scanner as the package is scanned at a hub within the delivery network, and/or the like. According to embodiments of the present invention, the billing, dimensional, and other package-related data may include information such as package dimensions and/or package weight, which may be used by the trailer utilization server to determine the total volume of the packages transported within the trailer. In particular, according to one embodiment, the trailer utilization server may divide the total volume of the packages by the interior volume of the trailer in order to determine the trailer utilization.

This process may be repeated for each trailer operating within the delivery network, until the trailer utilization server may determine the utilization for each trailer. Once the utilization for each trailer has been determined, the trailer utilization server may provide the utilization values to a network optimization server, which may analyze the utilizations and the delivery network schedule in order to determine the parameters for an delivery network, which may include, for example, adding, eliminating, and/or modifying scheduled routes. According to embodiments of the present invention, this network optimization process may be a continual, iterative process.

System Overview

Reference is now made to FIG. 1, which provides a block diagram of one type of system that may be used in order to determine the utilization of one or more trailers operating within a delivery network and, where possible, determine the parameters for an optimized delivery network, based at least in part on the determined utilizations. As shown, embodiments of the overall trailer utilization system may include a trailer utilization server 100 and a network optimization server 110, among other components. According to one embodiment, the trailer utilization server 100 and network optimization server 110 may comprise separate servers, or similar network entities, (as shown) in communication with one another over a wired or wireless network, including, for example, a wired or wireless personal area network (PAN), local area network (LAN), wide area network, (WAN), and/or the like. Alternatively, as discussed in more detail below with regard to FIG. 5, the functionality described herein and associated with the trailer utilization server 100 and network optimization server 110, respectively, may be performed by separate application modules stored on the same server, or similar network entity. In addition, as one of ordinary skill in the art will recognize in light of this disclosure, while reference is made throughout this disclosure to a “server,” embodiments of the present invention are not limited to a client-server architecture. In contrast, any central or distributed computer or network system may likewise be used to perform the functionality described herein without departing from the spirit and scope of embodiments of the present invention.

According to one embodiment, the trailer utilization server 100 may be configured to receive package-related data from various sources at various different times throughout a package delivery cycle, and use this information to determine the utilization of at least one trailer operating within the delivery network. Once the trailer utilization server 100 determines the utilization for each trailer operating within the delivery network, the trailer utilization server 100 may provide the utilization information to the network optimization server 110, which may be configured to determine the parameters for an optimized delivery network, which may include, for example, eliminating, adding, and/or modifying scheduled routes, among other actions.

According to one embodiment, the package-related data may include, for example, “billing data,” “scan data,” “dimensional data,” “trailer data,” and/or the like, each of which is discussed in more detail below. As shown, this and other package-related data may be stored in one or more databases associated with or accessible by the trailer utilization server 100 including, for example, a billing database 200, a scan database 300, a dimensional database 400, and a trailer database 500, among other databases. While shown as separate databases associated with each of the different types of data, as one of ordinary skill in the art will recognize in light of this disclosure, some or all of the package-related data may be stored in the same database associated with or accessible by the trailer utilization server 100.

According to one embodiment, “billing data” may refer to information provided by a customer at the time he or she is placing a shipping order. Referring to FIG. 2, an order may be placed in various locations and through various methods, including, for example, at a carrier store 210, at a carrier hub 220, at a customer location 230, and/or through the Internet 240, among other locations and methods. When placing the order, a customer may provide billing information related to the package, including, for example, the destination, billing weight, and/or dimensions of the package, level of service, and/or other related information. The billing weight provided by the customer may correspond to an actual weight of the package or an estimated weight. In particular, a customer who has a scale may weigh the package and provide the actual weight when placing the shipping order. In many instances, the customer may be a commercial customer. If the customer does not have a scale, the customer may, instead, provide an estimated weight of the package. In regard to the dimension of the package, according to one embodiment, the dimensions provided by the customer may include the actual or estimated height, width, and/or length of the package that is being shipped. The information provided by the customer, which is referred to collectively as “billing data,” may be input by the customer him- or herself or by a representative associated with the delivery service into a computing device (e.g. personal computer (PC), laptop, etc.). The billing data may thereafter be transmitted (e.g., periodically in batches or in real-time) over a wired or wireless network (e.g., wired or wireless PAN, LAN, WAN, etc.) to and stored in the billing database 200, such that the billing data may be accessed by the trailer utilization server 100. According to one embodiment, in addition to the information provided by the customer, the billing data may further include a tracking number assigned to the package at the time the order is input into the computing device. Like the information discussed above, the tracking number may likewise be transmitted to the billing database 200 over the wired or wireless network.

According to one embodiment, “scan data” may refer to information obtained when a package is scanned as the package is loaded into or unloaded from a trailer prior to or following transport. Scan data may include, for example, a tracking number associated with the package, the number of the trailer in which the package is being transported, at both the time of loading into and the time of unloading from the trailer, and/or the like. In particular, referring to FIG. 3, if the package 310 is being loaded into the trailer 330, a scanner 320 may scan the package 310 for a unique identifier code, such as the tracking number. Scanning often occurs at the carrier hub facility but may occur at any location the package is loaded or unloaded. According to one embodiment, the scanner 320 may capture the unique identifier code, along with the number of the trailer 330 into which the package 310 is being loaded, and transmit the captured information to the scan database 300 (e.g., periodically in batches or in real time) over a wired or wireless network (e.g., wired or wireless PAN, LAN, WAN, etc.), where the information may be stored and, therefore, accessible by the trailer utilization server 100. Similarly, as shown in FIG. 3, if the package 310 is being unloaded from the trailer 330, the scanner 320 may scan the package 310 for the unique identifier code, along with the number of the trailer 330 from which the package 310 is being unloaded, and transmit the captured information to the scan database 300 (e.g., periodically in batches or in real time) over a wired or wireless network (e.g., wired or wireless PAN, LAN, WAN, etc.), where in the information may be stored and, therefore, accessible by the trailer utilization server 100. According to one embodiment, the unique identifier code may be a code such as a bar code, MaxiCode, or other type of code that may be employed to store information such as a unique identifier code of a package. The scanner employed may be a scanner that can scan a unique identifier code, such as a bar code or MaxiCode, and decode the unique identifier code. Many well known scanners can read such codes, including, for example, laser scanners and CCD imaging scanners. An example of the type of scanner and decoding system that can be employed in this system may be found in U.S. Pat. Nos. 4,874,936, 4,896,029, and 6,094,509, which are hereby incorporated by reference.

“Dimensional data” may refer to the height, width, and/or length of the package obtained, for example, when the package is scanned by a dimensional scanner at various and multiple points during the shipment of the package. In particular, as shown in FIG. 4, a dimensional scanner 420, which may be located throughout the shipment process, and according to one embodiment, may be located at carrier hubs, may scan the package 410 to obtain the height, width, and/or length of the package 410. Once captured, the dimensional scanner 420 may transmit the dimensional data (e.g., periodically in batches or in real time) over a wired or wireless network (e.g., wired or wireless PAN, LAN, WAN, etc.) to the dimensional database 400, from which the dimensional data may be accessible by the trailer utilization server 100. According to one embodiment, dimensional data captured by dimensional scanners 420 may serve as a proxy for billing data not provided by the customer or for inaccurate billing data provided by the customer, among other uses. In other words, according to one embodiment of the present invention, information regarding the dimensions of the package may be obtained from the customer at the time of shipping the package (i.e. as billing data) and/or from the dimensional scanner at various points within or during the delivery process (i.e. dimensional data). The dimensional scanner 420 employed may be a scanner that can determine the length, width, and height of a package, among other measurements. The dimensional scanner may utilize optics, sensors, lasers, transducers, mirrors, and/or prisms, among other components, to determine the height, length, and weight of a package. An example of the type of dimensional scanner that can be employed in this system may be found in U.S. Pat. Nos. 6,952,628 and 5,672,815, which are hereby incorporated by reference.

Finally, according to one embodiment, “trailer data” may refer to the physical information about each trailer operating within the delivery network, including, for example, the trailer number, type, length, and/or volume. As noted above, the volume of the trailer may be utilized by the trailer utilization server 100 in determining the percent utilization of the trailer. According to one embodiment, trailer data may be stored in the trailer database 500 located on or accessible by the trailer utilization server 100.

Referring now to FIG. 5, a schematic diagram of a central server 500, or similar network entity, configured to determine trailer utilization and determine the parameters for an optimized delivery network, according to one embodiment of the invention, is provided. As used herein, the designation “central” merely serves to describe the common functionality the server provides for multiple clients or other computing devices and does not require or infer any centralized positioning of the server relative to other computing devices. As may be understood from FIG. 5, in this embodiment, the central server 500 may include a processor 510 that communicates with other elements within the central server 500 via a system interface or bus 545. Also included in the central server 500 may be a display device/input device 520 for receiving and displaying data. This display device/input device 520 may be, for example, a keyboard or pointing device that is used in combination with a monitor. The central server 500 may further include memory 505, which may include both read only memory (ROM) 535 and random access memory (RAM) 530. The server's ROM 535 may be used to store a basic input/output system 540 (BIOS), containing the basic routines that help to transfer information across the one or more networks.

In addition, the central server 500 may include at least one storage device 515, such as a hard disk drive, a floppy disk drive, a CD Rom drive, or optical disk drive, for storing information on various computer-readable media, such as a hard disk, a removable magnetic disk, or a CD-ROM disk. As will be appreciated by one of ordinary skill in the art, each of these storage devices 515 may be connected to the system bus 545 by an appropriate interface. The storage devices 515 and their associated computer-readable media may provide nonvolatile storage for a personal computer. It is important to note that the computer-readable media described above could be replaced by any other type of computer-readable media known in the art. Such media include, for example, magnetic cassettes, flash memory cards, digital video disks, and Bernoulli cartridges.

A number of program modules may be stored by the various storage devices and within RAM 530. Such program modules may include an operating system 550, a trailer utilization module 560, and a network optimization module 570. The trailer utilization module 560 and network optimization module 570 may control certain aspects of the operation of the central server 500, with the assistance of the processor 510 and the operating system 550. For example, as discussed in more detail below with regard to FIGS. 6-8, according to one embodiment, the trailer utilization module 560 may be configured to receive and aggregate data from multiple different sources at multiple different times throughout a package delivery cycle and to utilize the data to determine the utilization for at least one trailer operating within the delivery network. The network optimization module 570 may receive information from the trailer utilization module 560 and may determine the parameters for an optimized delivery network, which may include, for example, the addition, removal, and/or modification of routes in the delivery schedule. While not shown, according to one embodiment, the storage device 515 and/or memory 505 may further store the trailer database 500, which, as discussed above, may store trailer data that may be used to determine trailer utilization in accordance with embodiments of the present invention.

Also located within the central server 500 may be a network interface 525, for interfacing and communicating with other elements of a computer network. It will be appreciated by one of ordinary skill in the art that one or more of the central server 500 components may be located geographically remotely from other central server 500 components. Furthermore, one or more of the components may be combined, and additional components performing functions described herein may be included in the central server 500. While the foregoing describes the software of embodiments of the invention in terms of modules by way of example, as one of ordinary skill in the art will recognize in light of this disclosure, the software associated with embodiments of the invention need not be modularized and, instead, may be intermingled or written in other non-modularized formats.

Method for Determining Trailer Utilization

Reference is now made to FIGS. 6-7, which depict a method for determining the utilization of an individual trailer, according to one embodiment of the present invention. As shown, the process may begin when a customer places an order to ship a package and, in so doing, provides shipping data related to the shipment of the package (Block 600). The customer shipping order may be placed in various locations and through various methods, including, for example, at the carrier store, at the carrier hub, at the customer location, and/or through the Internet, among other locations and methods. This shipping data provided by the customer may include, for example, the destination, billing weight, and/or dimensions of the package, level of service, and/or other related information. As discussed above, some or all of the shipping information or data provided by the customer may be input into a computing device (e.g., personal computer (PC), laptop, personal digital assistant (PDA), etc.) and transmitted to (e.g., periodically or in real time via a wired or wireless network) and stored as billing data in the billing database 200 accessible by the trailer utilization server 100.

As depicted in FIG. 6, once the customer places the order and provides shipping data related to the package, the package may, at Block 610, be sent to a hub, where the package may be aggregated with other packages. While at the hub, the package may be assigned to a trailer (Block 620). Also, while at the hub, the package may, at Block 630, be scanned for dimensions by a dimensional scanner. In particular, the dimensional scanner may scan the package for its height, width, and/or length, in order to obtain the dimensional data of the package. As discussed above, upon capturing the dimensional data, the dimensional scanner may transmit (e.g., periodically or in real time via a wired or wireless network) the dimensional data to the dimensional database 400, where the dimensional data may be stored and subsequently accessed by the trailer utilization server 100. According to one embodiment, the package may pass through more than one dimensional scanner during its shipment from origin to destination. Furthermore, the package may be scanned as it is loaded onto the trailer (Block 640). The purpose of scanning the package while it is being loaded onto the trailer may be to generate scan data, which, as discussed above, may be transmitted to and stored in the scan database 300 accessible by the trailer utilization server 100. Scan data may include the number of each trailer in which the package was or is being transported.

Once the package is loaded onto the trailer, the trailer utilization server 100 or, in one embodiment, the trailer utilization module 560 executed by the processor 510 on the central server 500, may, at Block 650, obtain from the scan database 300 an indication of each package that is assigned to the trailer. In addition to obtaining each indication, the trailer utilization server 100 or module 560 may, at Block 660, further obtain package-related data including, for example, billing data from the billing database 200, dimensional data from the dimensional database 400, scan data from the scan database 300, trailer data from the trailer database 500, and/or other similar information related to each package that may be used to determine trailer utilization. In order to determine utilization, the trailer utilization server 100 or module 560 of one embodiment may take into account the volume of each package transported in the trailer, wherein in order to determine volume, the trailer utilization server 100 or module 560 may use, for example, the dimensions and/or weight of each package.

In particular, as shown in FIG. 7, upon obtaining from the scan database 300 the indication of the packages assigned to the trailer, as well as the package-related data from, for example, the billing database 200, dimensional database 400, scan database 300, trailer database 500, and/or the like, the trailer utilization server 100 or module 560 may, at Block 700, first determine the dimensions of each package assigned to the trailer. To determine the dimensions of a package assigned to the trailer, the trailer utilization server or module may obtain the dimensions of the package from the billing data provided by the customer and stored in the billing database 200. As noted above, the dimensions may either be actual or estimated by the customer. If the package is scanned by the dimensional scanner, then the dimensional data stored in the dimensional database 400 may include the dimensions of the package. In this case, the dimensions from the dimensional data may be substituted for the dimensions from the billing data because the dimensions from the dimensional data may be more precise.

Next, the trailer utilization server 100 or module 560 may, at Block 710, determine the weight of each package assigned to the trailer. To determine the weight of the package assigned to the trailer, the trailer utilization server or module may obtain the billing weight of the package from the billing data provided by the customer. The billing weight may be either actual or estimated by the customer. Alternatively, the trailer utilization server or module may instead obtain the weight of the package from dimensional data provided by the dimensional scanner. In particular, package dimensions received by the dimensional scanner may be used to determine a dimensional weight of the package. Dimensional weight may be a calculated measurement and may be the equivalent weight of the package based upon the dimensions of the package. For example, if the customer ships an item in the package that is designed to carry items of greater weight than the item shipped, the dimensional weight of the package may be greater than the actual or estimated weight provided by the customer. In other words, if the dimensions of the package received by the dimensional scanner indicate that the package is a five pound equivalent sized box, the dimensional weight may be five pounds, even if the item shipped weighs only one pound. If the billing weight is not provided in the billing data, the trailer utilization server or module may use the dimensional weight as the weight of the package. Additionally, dimensional weight may be substituted for the billing weight as the weight of the package if the dimensional weight is calculated to be greater than the billing weight. Furthermore, if billing weight is not provided in the billing data and the package has not been scanned by a dimensional scanner in order for a dimensional weight to be calculated, the trailer utilization server or module may use as the weight of the package the average weight of the packages being shipped in the same trailer for which there is weight-related data. If there is no weight-related data for the other packages being shipped in the same trailer, then a weight/volume factor may be used to estimate the weight of the package.

According to one embodiment, the trailer utilization server 100 or module 560 may, at Block 720, determine the volume of each package assigned to the trailer. To determine the volume of each package, the trailer utilization server or module may use the dimensions of the package assigned to the trailer to calculate the volume of the package. If neither the billing data nor the dimensional data include the dimensions of the package, the volume of the package may be estimated by various methods. In some embodiments, the volume may be estimated as the historical average volume of the package, based on the weight of the package. This historical average volume may be obtained by sampling packages of various weights, measuring the volume of each sample package, and determining a relation between the weight of each sample package and its corresponding volume. An example of a system and method for estimating the volume of a package that may be utilized in this system may be found in U.S. application Ser. No. 11/457,015, filed Jul. 12, 2006, and entitled “Systems and Methods for Forecasting Container Density,” which is hereby incorporated by reference. Accordingly, if the billing data and dimensional data do not include package dimensions, the trailer utilization server 100 or module 560 may reference a lookup table (e.g., residing in the memory 505 or the memory 515) that may include a mapping of weights to historical average volumes in order to obtain the estimated volume for the package based on the weight of the package.

Once the volume of each package transported by the trailer has been determined, the trailer utilization server or module may determine the utilization of the trailer (Block 730). In particular, the trailer utilization server or module may calculate the total volume of the packages assigned to the trailer to determine the total volume occupied by the packages in the trailer. The trailer utilization server or module may then divide the total volume occupied by the packages in the trailer by the total volume of the trailer, which, as discussed above, may be obtained from the trailer data stored in the trailer database 500. The resulting percentage may be the utilization for the individual trailer. To illustrate, one example of a formula for calculating trailer utilization is as follows:

${U_{t} = \frac{\sum\limits_{{Pt} = 1}^{n}V_{Pt}}{V_{t}}},$ where Pt is a package assigned to trailer t, n is the number of packages assigned to trailer t, V_(Pt) is the volume of a package assigned to trailer t, V_(t) is the interior volume of trailer t, and U_(t) is the utilization of trailer t.

Referring to FIG. 8, once the utilization has been determined for the individual trailer, the trailer utilization server or module may, at Block 800, perform the same process for each trailer in the delivery network or in a subset of the delivery network in order to determine the utilization of each trailer in the delivery network or the subset of the delivery network. The determined trailer utilizations may, at Block 810, be analyzed in order to determine the parameters for an optimized delivery network. In particular, in some embodiments, the network optimization server 110 or, in other embodiments, the network optimization module 570 executed by the processor 510 on the central server 500, may obtain the calculated utilizations and may perform various algorithms and procedures to determine the parameters for an optimized delivery network. In other embodiments, the data may be manually analyzed in order to identify opportunities for optimization of the delivery network. To optimize the delivery network, many actions may be taken, including, for example, eliminating routes from the schedule, adding routes to the schedule, altering the times in which routes are scheduled, assigning larger or smaller trailers to specific routes, and/or other actions that may be designed to optimize the delivery network and its schedule (Block 820).

In various embodiments, the optimization process may be an iterative process that may be continually performed in order to continually improve the efficiency of the delivery network. Accordingly, the trailer utilization server or module may continually determine the utilization of the trailers in the delivery network, and the parameters of an optimized delivery network may be continually determined either through the use of the network optimization server or module or through manual optimization.

In other embodiments, if trailer utilization can be determined before the scheduled route of the trailer has begun, then the delivery network may be optimized “on-the-fly.” If two trailers, for example, are scheduled to travel from the same origin to the same destination, and the utilization of each the trailers is such that the packages in both trailers could be adequately combined into one of the two trailers, then one of the routes could be eliminated. Additional types of related actions may be taken to preemptively optimize the delivery network.

The present disclosure is not limited solely to the shipping industry.
